OrphaNet reports on an ongoing systematic survey of literature in order to provide an estimate of the prevalence of rare diseases in Europe, which presumably could be generalized to the entire world. The current version of the report, which is continually being updated, supports anecdotal data regarding the prevalence of Facioscapulohumeral MD (FSHD) as compared to other muscular dystrophies. The current update of the report on Prevalence or reported number of published cases listed in alphabetical order of disease lists FSHD as occurring in approximately 7 out of 100,000 individuals. This is compared to 5 out of 100,000 individuals for Duchenne and Becker muscular dystrophy, formerly considered the most prevalent form of muscular dystrophy.
